I've been having my usual ordeal when it comes to finding items of clothing that fit me correctly, and after ordering around 10 wetsuits have found one that feels tight, yet doesn't take 5 minuites to take off. However, I'm worried about the underarm area as I've read online that it should be flush to the skin, with no space or room for air, but this one has, and I can't work out if that's permissable or it will cause me issues during the swim.

This is for my first Sprint tri in 4 weeks, but I'd like to use it for my future races, and as they're not cheap I want to be happy with it
